this pyrenomycete we found twice last week, on Fagus logs in the Bavarian Forest near Spiegelau (Germany). It grows in a corticiod fungus I could not yet determine.

As I also found a Helminthosphaeria aff. hyphodermae (perhaps I show later because it is slightly deviating) in Peniophorella pubera, I think the genus could be a hint. But I do not find a species with such spores.

The dark spores become septate outside the ascus - assymetrically. They measure about 10-11,5(12)/5-5,5(6) µm.
